Aerospike vs Redis
Elaborating the performance comparison of these great in-memory databases. Here , I am covering the performance comparison of reading part.
We've been using Redis database since very long, it is one of the most go-to, most popular and widely used in-memory database.
Currently, I am working for a digital advertising firm, where we used to take part in real-time advertising auctions, handles around 400k-500k bid-requests per second, our cloud servers (we call them bidder-servers) are constantly bidding & serving a large number of ads globally. We are using REDIS as well for realtime data retrieval. It's really important for bidder-servers to read the very latest key information regarding each campaign in a fastest manner.
Comparison Environment
- AWS instances for Redis and Aerospike. Configured both databases in order to utilize all resources and handle maximum possible load.
AWS Ec2 Instances - r4.4xlarge
- A set of few EC2 instances ( as clients) in the same region where Aerospike and Redis are hosted.
AWS instances - c5.xlarge
Benchmark & Results
Scenario: Total reads: 1M, Concurrency: 90
Client Instances
Total req/sec handled in
Redis
Total req/sec handled in Aerospike
1
70 - 90k
270 - 350k
2
138k - 150k
380-420k
10s
150-200k
450-480k
Few Snapshots:
- 1.Running benchmark test from 1 client ec2 instance:
Aerospike Benchmark - 350+ req/sec
Redis Benchmark - 138k+ req/sec
2. Running benchmark on 2 client instances together
Aerospike Benchmark - total 400k+ req/sec
Redis Benchmark - total 135k+ req/sec
Conclusion
We can't say for given resources neither Aerospike nor Redis performed bad. However, Aerospike performed significantly high in all the tests here. Definitely it's a better choice if you are searching for DB which gives much faster Reads other than Redis.
